To all whom it may concern:

Be it known that 'I, Dr. ALBERT LANG, a subject of the Grand Duke of Baden, Germany, residing at Karlsruhe, in Baden, Germany, have invented certain new and useful Improvement in the Heating and-Cooking of Liquids, Solid Substances, andMixtures of Liquids and Solid Substances, of which the following is ing had therein ing. 1

My invention relates to a device for rapidly heating liquids, ormixtures of liquids and solid substances, or evensolid substances themselves. According to the invento the accompanying drawtion the heat of reaction of substances contained in a shell or cartridge is utilized to produce a very high temperature, the reaction being affected by the ignition of-metals small in amount in any case;

or metallic substances with bases such as oxygen-carriers orsulfur without the introduction of air combustion. The heating tube, in which the cartridge is ignited, is conical material to the bottom thereo is prevented by a layer of suitable material; the remains of the cartridge can therefore'easily be removed from the tube .after use. end of the tube may be closed loosely resting thereon, and a perforated cap can be disposed over the lid, so that any gases developed can escape easily and without obstruction; such gases should be very The heating in its use as employed in by a lid device is not limited" therefore cases wherein the evolution of matter. Hence the device can be used anywhere and by anybody.

In the accompanying drawing: Figure '1.

shows a section of a suitable heating or cookcover n of the receptacle 0.

ing apparatus foruse according to the in vention. Fig. 2 shows a plan of the cover.

' Referring now to Figs. 1 and 2.,the heating cartridge a with its fuse?) is arranged in the lower conical part I: of a tube Zprovided at its upper end with an enlargement m resting on the edge of an opening in the largement m is seated a lid 72 which by reason of its weight restricts the escape of gases, but is slightly raised if an excess pressure occurs to allow the gases to escape,

passing. out through the cover n, turning it through a quarter turn by means a specification,--re ference be- 'eration of gas,

and cakin of the burnt,

The upper gases did not On the en- -guided in the cap 8 bya bolt 1' and a collar t on the bolt prevents the lid from closing the occurs. The,c ap s is provided with a flange u held 1n position .by the projections '0 on and it can easily be removed by of the notches For use, the cover 12. is placed on the re ceptacle 0 after the substances to be heated have been inserted therein, and then the heating tube Z is passed through the cover n. The heating cartridge is now inserted into the tube and the fuse b may be ignited before doing so. After the cartridge has been inserted the lid ;0 is applied together with the cap s which is securedon the cover at: the lid p then rests on the edge of the heating tube, thus'closing the latter. Thegenin consequence of the particular composition 'of the cartridge,is very slow, but should'an excess pressure occur,

7 the gas will escape through the openings at openings at 1 when a rapid rise of pressure 9 after lifting the lid 7). If large quantities are to be heatedor from the tube.

Having. now particularly described and ascertained the nature of my said invention and in what manner the same is to be op-.

2. In a heating and cook receptacle of the character described,] having a cover, in combination, a conical tube adaptedfor the reception of a heating cartridge, a flange at the upper end of sa1d tube resting on the edge of an opening in said cover, a lid upon said'flange, a cap coverin said lid and provided with o enings in ts upper face for the exhaust o the gases of combustion upon if the cooking tempera-' ture is to be maintained for a long time a p number of cartridges may be'successively burnt and all subsequently removed together a I the liftin of said lid by said gases, a bolt and nut or limiting the lifting movement of said lid, a flange on said cap, projections on said cover holding said flange in position, and notches in said flange allowing the pas sage of said projections for removing the cap, substantially as described.

In testimony whereof I afiix my signature in presence of two Witnesses.
